The earliest mention I have seen of a tomato that would fit the description of what we have today is of a variety from the Philippines about 100 years ago.

There are 5 separate mutations to the same gene that result in black tomatoes. It disables conversion of chlorophyll into the biochemical precursors of lycopene. The end result is that there are 5 separate mutations, but only one phenotype. All varieties that exhibit the same mutation can be presumed to be directly related genetically.

Notice that Black Plum is unique in this list. It is very probable that it represents a recent mutation. If you look at the group with Russian derived names, you will see that they cluster together which seems to indicate a single common point of origin.
